Eugenio Valderrama recently had a paper accepted for publication in the journal Molecular Phylogenetics and Evolution. In it he details how he discovered new phylogenetic markers that are needed to resolve relationships amongst species of the genus Renealmia (Zingiberaceae) that is the only genus in the family native to the neotropics. The markers were designed to be short in length and thus suitable for use on the often degraded DNA that is recovered from herbarium specimens. The genus is also found in Africa and the data will be used to determine whether there are differences in diversification rates between African and neotropical lineages.
